4 Claims. (01. 261-30) My invention relates to new and useful imsorbent material or sheet 4 suspended or otherprovements 'in air cooling devices in which air wise positioned in the body portion of said device is injected into the device, humidified therein by means of a rod 5 attached to said body portion and then discharged therefrom into the air of a l and by fasteners 6 near the bottom of said 5 room, and has for its objects to provide an air sheet. The sheet is held at an inclined plane 60 cooling apparatus which is very light and adapted near its top by means of a cross bar 7 and in to be attached to an electric air circulating fan this position the sheet 4 may receive water as it of the kind used in circulating air in a room; to drops from the apertures 3. Under the sheet provide such apparatus in form whereby it may 4 at the place where the water drops thereon is 10 be entirely mounted on and carried by said fan; placed a strip of non-absorbent material such as as to provide it in form so that it may be attached rubber or rubberized cloth 8 extending across the to and carried entirely by the oscillating portion top of the sheet and by means of which the water of an oscillating fan and may oscillate therewith; dripping on said sheet is caused to be diffused to provide an absorbent sheet from which water across the entire sheet and thence downwardly may be evaporated in said device in form whereby over its entire surface. In the drawing this 70 the water thereon is readily diffused thruout the non-absorbent material is shown as being foldsheet; to provide a simple means whereby water ed within the hem of said sheet, which constitutes may be transferred to said sheet; and to promerely an inexpensive way of backing the sheet vide means of forcing or jetting the moist air with said non-absorbent material.

This form of attachment permits the 05 1 represents generally the shell, frame or body apparatus t be readily Placed the fan and portion of the device, 2 a water reservoir thereon removed therefrom when it is not desired to use or therein, 3 a discharge port or outlet for said the same. The fan is shown as located on a wall reservoir thru which water may escape therefrom bracket 13 but may rest on the floor or a table or 5 by force of gravity to moisten or saturate an abany other customary place. The pair of lower o hooks 11 hook over the fan guard 14 of the fan, and for a larger fan the pair of upper hooksare used instead. Additional pairs of books for other sizes of fans may be provided.

In operation, water or other liquid is placed in the reservoir 2 and the device is hooked on the fan guard 14 of the fan 12. The device is designed so that when it is attached to the fan its bottom is positioned above the horizonof the base of the fan, so that it may clear any surface whereon the fan may rest and permits of the oscillation of the oscillating part of an oscillating fan when the device is attached to such type of fan. The device is completely carried on the fan or oscillating part thereof as aforesaid. The hooks 11 are positioned on the device so that it will not only clear the base horizon as aforesaid but will position the inlet 9 in alignment with the fan so that the current of air from the fan will be directed into said inlet. The apparatus is stable enough so that when the reservoir is filled with water, it will not overbalance the fan.

The water in said reservoir drips on the sheet 4 thru the apertures 3 and is diffused thruout the sheet. Any surplus water is caught in the catch basin aforesaid.

Air entering the inlet 9 under draft created by the fan 12 is directed against the sheet 4 which is saturated or moistened as aforesaid, causing the air to absorb said moisture from said sheet. Preferably the sheet is located within a humidifying chamber such as is shown in the drawing, said chamber being a closure except for the water inlet 3, the air outlets 10 and the air inlet 9, and in this form it not only causes the air entering the chamber to become thoroughly saturated but permits of its being forced or jetted thru an outlet or outlets 10 into the room. The total cross sectional area of the outlets 10 are preferably restricted with relation to the cross sectional area of the inlet 9, to cause pressure to be built up in the humidifying chamber sufficient to cause the air to be jetted from said chamber with an asperating effect as aforesaid. It is also preferred to position said outlet or outlets so that the air therefrom will be jetted upwardly as aforesaid, and when on an oscillating fan it is also advantageous to have a jet or jets so disposed on either side of a plane perpendicular to the axis of the inlet 9 and positioned substantially radially of said axis, so that with the oscillation of said apparatus the room is in effect sprayed with the humidified air therefrom.

Having thus fully disclosed my invention, what I claim and desire to secure by Letters Patent is:

1. An air cooling device adapted to be mounted on an air circulating fan of the kind used for circulating air in a room, and with said device comprising a body portion, a chambertherein wherein air may be humidified, a water reservoir thereon, means of transferring water from said reservoir to an absorbent material, an absorbent material as aforesaid located in said chamber and adapted for the evaporation of water therefrom and positioned to receive a current of air injected into said chamber thru an air inlet thereto, a catch basin positioned below said absorbent material, an air inlet in said chamber as aforesaid the axis of which inlet is substantially horizontally disposed, a plurality of air outlets from said chamber and with said outlets upwardly directed and substantially radially disposed with reference to said axis of said inlet, and means of mounting said device entirely on a fan as aforesaid in manner to cause a current of air from said fan to be directed into said chamber thru said inlet thereto.
